Nested setTimeout alternative?

Question

I need to execute 3 functions in a 1 sec delay.

for simplicity those functions are :

console.log(\'1\');
console.log(\'2\');
console.log(\'3\');
         


        

Answer 1

There are here two methods. One with setTimeout and anotherone with setInterval. The first one is better in my opinion.

for(var i = 1; i++; i<=3) {
  setTimeout(function() {
      console.log(i);
    }, 1000*i);
}
// second choice:
var i = 0;
var nt = setInterval(function() {
      if(i == 0) return i++;
      console.log(i++);
      if(i>=3) clearInterval(nt);
    }, 1000);
